Israel plans to deport former U.S. lawmaker and Green Party presidential candidate Cynthia McKinney and 20 other human rights activists who were aboard a relief boat seized by an Israeli naval ship Tuesday after it refused to stay away from an Israeli blockade of Gaza.

Authorities took the activists to Ben Gurion International Airport in Tel Aviv where they await deportation, according to a news report in Israel.

McKinney, a longtime advocate for Palestinians, said her Greek-flagged boat, the Spirit of Humanity, was carrying medical supplies, cement, olive trees and children’s toys to Gaza when it was intercepted by the Israeli navy.

The Free Gaza Movement organized the trip for the activists who hail from different countries, including Ireland, Britain and Bahrain.
